In motion capture, a standard procedure to obtain the bone motion is the use of skin markers. However, because of the relative motion of the skin and the bones, so-called soft tissue artefacts (STA), the recorded motion does not accurately describe the movement of the bones. To compute joint reaction forces and perhaps limit STA, most musculo-skeletal models use underlying joint models. The knee is usually modeled as a simple hinge joint. However such approaches do not lead to a better estimation of the real motion1. In this work the hinge joint is improved by taking into account the morphological features of the joint surfaces.

In this paper, the in-vivo loads of the knee joint provided by an instrumented prosthesis (Fregly et al., 2010, Lin et al., 2010, Kim et al., 2009) are compared to the results obtained from an implementation of the Klein Horsman data set (2007) in the AnyBody Modeling System. The lateral and medial knee contact forces are estimated directly from the knee modeled as a modified revolute joint. As such, this study presents what can be achieved by estimating the knee contact forces from a simplified knee model. [less ▲]
